Abstract: The present invention relates to a laminated glass for vehicle, including a first glass plate and a second glass plate joined to each other by an intermediate film, in which the first glass plate has a second main surface facing the intermediate film; the laminated glass has a first region with the second glass plate and a second region with no second glass plate in a plan view; the laminated glass has a filling portion that includes an electromagnetic wave transmission member and is disposed continuously from the second main surface on the second region toward a space between the first glass plate and the second glass plate in the first region to cross the entire boundary between the first region and the second region; and the second region is higher in transmittance of millimeter waves than the first region.

Abstract: A cover glass includes a chemically strengthened glass including a first main surface having an area of 12,000 mm2 or larger and a second main surface, and an anti-fingerprint treated layer provided on or above the first main surface. The chemically strengthened glass has a depth of compressive stress layer DOL of 20 μm or larger, has a tensile stress layer having a P2O5 content of 2 mol % or less, and has A×B of 135 or larger, provided that, among oxide components constituting the tensile stress layer, a total concentration of Li2, Na2O, and K2O is A mol % and a concentration of Al2O3 is B mol %. The anti-fingerprint treated layer includes a surface having a frictional electrification amount, as determined by Method D described in JIS L1094:2014, of 0 kV or less and −1.5 kV or more.
